Using the image below, please describe ganglion cells A, D, and Es activation levels, and how this would help us detect the edge pictured. Be sure to describe where the light is hitting on the ganglion cell and how this relates to the cell's activation.
Finally, please compare the activation level of A, D, and E to the activation level of B and C. Do they have greater activation? Do they have less activation? Why is that the case?
